If anything, they suffer from two of the problems that the 742 has, one if fired extensively the interrupted thread locking lugs in the receiver will stretch, when this gets bad enough the rifle is trash. As a deer rifle you'll probably never see this....Problem two is more nuisance than anything, the chamber on these rifles (and 742's and model 4's and 7400's and the new 750's) are hard to clean and lube. Without special attention they will rust, at times so bad the rim will be pulled off the fired case trying to extract it. I keep mine coated with silicone spray, this dries and so far has kept mine from rusting again.
